on their peripheries, of which the followingis a specification:

This invention is applicable, among other purposes or uses, to theturning or dressing of emery or other grinding Wheels of transversecurvature on their peripheries, suitable for grinding or dressing thebearingsurfaces of journal-boxes. The invention consists in acombination, with a revolving shaft or carrier of the Wheel or body tobe dressed, of a diamond or other cutter made capable of motion Vin atransverse relation to the rim or periphery of the Wheel, when saidcutter is directed by a curvilinear guide or pattern corresponding withthe shape of the body to.be turned, substantially as hereinafterdescribed.

In the accompanying drawing, which forms i part of this specification,Figure 1 represents a plan of a machine constructed in accordance withmy invention; Fig. 2, a side-view of the same; and Fig. 3, a partiallysectionalslotted tool-rest carried by a pivot or swivel-` pin, c, withina socket,`d., attached to the top of the frame at orlnear the endthereof, and

in line of the plane of the wheels rotation or thereabout, so that thecurved guide or pattern D may be set up or downand turned, as

required in the socket d, to bring the diamond or other cutter E inproper relation -to the periphery of the wheel or body to be turned butafter this adjustmentis'made the travel of the cutter E transversely tothe rim of said wheel or body is directed by the slot or slots e in theguide or pattern D, by means of a block, F, free to travel within saidslots and the movement of the sliding block F, gives t the necessarycurved contour to the rim ofthe revolving Wheel or body.

What is here claimed, and desired to be secured by Letters Patent, is-

In combination with the emery'or other grinding Wheel G,the curved guideor pattern D adjustable up or down and about the axis of the svivel-pin'c, the sliding-block F,

and the diamond or other cutter, E, adjusta-` ble through said black,substantially as specined.
